I have an 86 toyota pickup 4x4 EFI. A wire from the battery to the fuse box broke off due to the battery sliding around and I lost all power to everything. The copper crimp connector was still attached to the end of the wire as it had broken off the rest of the copper bar. So I took a new peice of wire and soldered it on to the bar and the truck works fine now, but three warning lights are now on the brake light, the charge light, and the A.T. oil temp light(even when cold). I wonder if the solder spread too far and created a connection that should not be so i was looking for a diagram of that part of the fuse box, with the 80 amp fuse, or someone who knows more about it than I do.

 

you broke the fusible link wire, it is the primary fuse and important, order a new one.

The lights are lit to indicate your battery is not charging, you will need to reasess after you get the wire in place.
